Abstract

<P>PROBLEM TO BE SOLVED: To correct the imaging time of image data stored in the storage media of image equipment into the appropriate time. <P>SOLUTION: If pictures are taken in an initial condition without setting the time of the image equipment, the elapse of time from immediately after the acquisition of image data to the next time setting is counted by a timer and a count value is stored in a main memory together with the image data and the imaging time. If the recording media is temporarily removed before the next time setting and if the imaging equipment is reset, the timer is reset. If the recording media is not removed after imaging, the imaging time stored in the main memory when the next time setting for the image equipment is carried out since the image data is acquired is corrected into the time equal to the current time minus the count value. When a plurality of images exist, the imaging time of the image selected by the user is corrected. <P>COPYRIGHT: (C)2003,JPO

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video device, a method for adjusting a photographing time thereof, and a storage medium storing a program for controlling the method.

[0002]

2. Description of the Related Art In video equipment such as VTRs, video discs, and digital still cameras, images and sounds obtained by photographing a subject are recorded as data on a recording medium.
In addition, some video equipment records the recording time such as shooting time and recording time as image data.In such video equipment, even when the power of the video equipment is turned off, the data recording time is managed. , Can be stored.

A conventional method of managing the shooting time in a video device will be described below with reference to FIG. Figure 7
FIG. 6 is a schematic diagram for explaining a flow of processing for managing shooting time in a general digital still camera.

When the digital still camera is shipped, when the digital still camera is reset, or when the recording medium is removed from the video equipment main body in order to change the recording medium, it is usually built in the digital still camera. The time of the built-in clock is in the initial state, and the actual time is, for example, as shown in (1) of FIG.
Even at 8:20 on the 17th of the month, the built-in clock is initially set to 0:00 on January 1, 2000, etc., as shown in (2) of FIG.

The user neglects to set the time of the built-in clock of the digital still camera, and a certain fixed time, for example, 2 hours and 5 minutes a day as shown in (3) of FIG. 7, elapses, and then (4) of FIG. When the subject is photographed and data such as image and sound is recorded at 10:25 on May 18, 2001 as shown in, the photographing time recorded on the recording medium at this time is the initial state. Relative time after a certain time ((3) 1 day 2 hours 5 minutes) from ((2) 0:00, January 1, 2000), January 2000, as shown in (5) of FIG. Two
It is 2:05 a.m.

After the subject is photographed, a certain time, for example, 7 days and 1 hour and 10 minutes as shown in (6) of FIG. 7, elapses. Then, as shown in (7) of FIG. 1
Even when the user sets the time of the built-in clock of the digital still camera at 1:35, the shooting time initially recorded in the recording medium is the relative time from the initial state, that is, FIG. 2000 (1) as shown in (8) of
It will be 2:05 on the 2nd of the month. Therefore, in the conventional digital still camera, the shooting time once stored in the recording medium cannot be corrected to reflect the time setting even if the time of the built-in clock of the digital still camera is set after shooting.

The time is set in the built-in clock of the digital still camera, and as shown in (9) of FIG.
By taking an image at 12:45 on May 27, 2015, the correct image capturing time will be displayed for the first time, for example, (10) in FIG.
As shown in FIG. 12, 12:45 on May 27, 2001 can be recorded on the recording medium. However, even in this case, the photographing time of the image photographed in the past is a relative time from the initial state, for example, as shown in (11) of FIG.
It is managed as it is at 2:05 on January 2, 2000, and this shooting time cannot be corrected. As a result, image data in which the correct shooting time is recorded and image data in which the incorrect shooting time is recorded are mixed, and the user cannot easily edit and manage the data.

[0008]

Generally, images, images,
In a video device in which sound and the like are recorded, the recording time is recorded as data in a recording medium together with the image and sound.
However, when the time setting of the built-in clock is not set in the video equipment before recording the image data, the shooting time is recorded as the time in the initial state. As described above, since the image data in which the wrong shooting time is recorded and the image data in which the correct shooting time is recorded are mixed in the recording medium, the user can change the image data according to the shooting time recorded in the recording medium. Editing and managing is not easy.

In order to correct such an incorrect photographing time, it is necessary to transfer the data to another device and manually edit the data. However, when the number of data is large, the user also has a heavy burden of editing the data.

In Japanese Patent Laid-Open No. 4-306079, the current date and time are generated as current time data and recorded on a video tape so that the user can easily manage and edit the tape after photographing the subject. There is disclosed a photographing device that can perform the above. However, this Japanese Patent Laid-Open No. 4-3
JP-A-60079 does not disclose that the photographing time of the image once recorded on the recording medium is corrected, and that the photographing time managed by the photographing device together with the images photographed in the past is not corrected. Can not.

The present invention has been made in order to solve the problems of the prior art as described above.
Provided is a storage medium storing a video device, a method for correcting the shooting time thereof, and a program for controlling the method, which can correct the shooting time of an image stored in a storage medium to an appropriate time in the past. The purpose is to do.

The video equipment according to the present invention includes a built-in clock, a counting means for counting the time elapsed immediately after the subject is photographed, and the time counted by the counting means for photographing the subject. It has a main memory that stores and manages together with each image data obtained from the image and the photographing time, thereby achieving the above object.

In the video equipment of the present invention, when the time of the built-in clock is set next after photographing the subject, the photographing time of the image stored in the main memory is changed from the current time to the counting means. It is possible to further include a time correction processing means for correcting the time obtained by subtracting the counted time.

In the video equipment of the present invention, after the subject is photographed, selecting means for selecting any image data whose image capturing time is corrected from the plurality of image data stored in the main memory, and the selecting means. It is possible to further comprise a time correction processing means for correcting the shooting time of the image selected in step 1 to the time obtained by subtracting the time counted by the counting means from the current time.

The video equipment of the present invention has a recording medium in which image data is recorded, which is removable from the video equipment main body, a means for detecting whether or not the recording medium is connected to the video equipment main body, and the recording medium. Can be configured to further include means for resetting the time counted by the counting means when the apparatus is once detached from the video equipment main body or when the video equipment is reset.

According to the video equipment of the present invention, when the time of the built-in clock is corrected, the photographing time of the image stored in the main memory is corrected according to the time difference between the time before correction and the time after correction. The time adjustment processing means may be further provided.

The method for correcting the photographing time of the video equipment of the present invention is as follows:
The step of storing in the main memory image data consisting of the image obtained by shooting the subject and the shooting time, counting the elapsed time immediately after shooting the subject, and storing the counted time together with the individual image data in the main memory And the shooting time stored in the main memory when the time of the built-in clock is set next time after shooting the subject by subtracting the counted time from the current time. The time is adjusted to a specified time, thereby achieving the above object.

The method for adjusting the photographing time of the video equipment of the present invention is as follows:
The step of storing in the main memory image data consisting of the image obtained by shooting the subject and the shooting time, counting the elapsed time immediately after shooting the subject, and storing the counted time together with the individual image data in the main memory The step of managing the shooting time of the selected image from the plurality of image data stored in the main memory after the shooting of the subject. Adjusting the time to a time obtained by subtracting the counted time from the current time, whereby the above object is achieved.

The method for adjusting the photographing time of the video equipment of the present invention is as follows:
Detecting whether or not a recording medium on which image data is recorded, which is removable from the video equipment main body, is connected to the video equipment main body, and when the recording medium is once removed from the video equipment main body, or When is reset, the time counted can be reset.

The method for adjusting the photographing time of the video equipment of the present invention is as follows:
When the built-in clock is corrected, the shooting time of the image stored in the main memory can be corrected according to the time difference between the time before correction and the time after correction.

The storage medium of the present invention stores a program for controlling the method for adjusting the photographing time of the video equipment of the present invention, thereby achieving the above object.

The operation of the present invention will be described below.

In a video device for recording images, sounds, etc., it is preferable that the user sets the time before photographing the subject. However, there are various ways of using the video equipment by the user, and shooting is not always performed after the time is set.

Therefore, according to the present invention, in a video equipment for recording images, sounds, etc., the time elapsed immediately after the subject is imaged is counted by a timer or the like, and together with the image data consisting of the image and its photographing time, The counted value is stored and managed in the main memory. The image data is also recorded on the recording medium.

By the time the next time the internal clock is set, if the recording medium is once removed from the video equipment body or the video equipment is reset, the counting means counts. The time is reset.

When the subject is photographed and the image data is stored in the recording medium, and the recording medium is not once removed from the video equipment body after the photography, the time of the video equipment is set next after the photography. At this time, the shooting time of the image stored in the main memory is corrected to the time obtained by subtracting the counted time from the current time. This corrected time is updated as the correct shooting time of the stored image on the recording medium. As a result, the user does not set the time of the built-in clock, shooting is performed in the initial state, and the shooting time once recorded on the recording medium corresponds to the initial state before the time setting of the built-in clock. Even when the time is set in the built-in clock later, the shooting time can be corrected to the correct time.

After the photographing time is corrected to the correct time,
Image data can be recorded and managed in the same manner as with conventional video equipment. Also, when shooting is performed after the built-in clock is set to the time, as with conventional video equipment,
The correct shooting time according to the set time is recorded on the recording medium.

When the time of the built-in clock is corrected, a time difference occurs between the time before correction and the time after correction.
The shooting time stored in the main memory is corrected according to the time difference between the time before correction and the time after correction. Even for images taken in the past, the time management data stored in the main memory should always be used to manage the image shooting time and the time of the built-in clock built into the video equipment body. You can

When there are a plurality of image data, the user selects the image data to correct the photographing time of the selected image. This makes it possible to correct the shooting time of an arbitrary image shot in the past, regardless of the number of image data stored in the recording medium. Also, even if the shooting time was corrected in the past,
The time management data stored in the main memory allows the image data to be managed so that the image capture time can always be adjusted unless the storage medium is removed or the video equipment is reset.

It is connected to each of the processing unit 8, the timer processing unit 9, and the clock processing unit 10.

The input device 1 is composed of operation buttons, and operates to control various functions of the video equipment.
A command is input.

The image capturing device 2 has a CCD, a lens, etc., and captures an image of a subject to capture image data into the video equipment. The image data is data of a captured image acquired by the image capturing device 2,
It consists of an image and the time of image capture.

The image captured by the image capturing device 2, camera information and the like are displayed on the monitor screen provided in the display device 3. By confirming various images, camera information, etc. displayed on the monitor screen, the user can easily operate the camera.

The image 5a picked up by the image capturing device 2 and its shooting time 5b are recorded as image data 15 in the recording medium 5 and stored. The recording medium 5 is attachable to and detachable from the main body of the video equipment. When the video equipment is a digital still camera, for example, a storage medium having a memory function such as a compact type flash memory or smart media can be used.

In the main memory 6, a main program and various data 6a, image data 6c, and time management data 6b are recorded and stored. The main program and various data 6a are a series of control information for operating the CPU 4, each device connected to the CPU 4,
It is processing information output from the part. The time management data 6b includes the time of the clock processing unit 10 and the recording medium 5.
It shows the time difference from the shooting time of the image recorded in 1. When shooting is performed in a state where the built-in clock is not set in the clock processing unit 10, when the recording medium 5 is exchanged and shooting is performed. Used for etc. The time management data 6b is recorded together with the image data 6c and is managed by the main memory 6 until the recording medium 5 is removed from the video equipment body or the video equipment is reset.

The image selection processing section 7 is used by the user to select the image data for which the photographing time is desired to be corrected from the image data stored in the recording medium 5. In the image selection processing unit 7, the image data 6c and its time management data 6b are selected from the main memory 6 based on the operation and command input from the input device 1, and the selected image data 6c and its time management data are selected. 6b is supplied to the time correction processing unit 8 and the time of the photographing time is corrected.

In the time correction processing unit 8, when the user sets the time of the built-in clock, the shooting time of the image stored in the main memory 6 changes from the current time to the value of the counter in the timer processing unit 9. Is corrected to the time obtained by subtracting. When the user corrects the time of the built-in clock, the time correction processing unit 8 determines the shooting time of the image stored in the main memory 6 according to the time difference between the time before correction and the time after correction. Is fixed. The corrected time is
The time when the image is actually shot is written in the recording medium 5, and the time management data 6b managed in the main memory 6 is reset. When correcting the shooting times of a plurality of images, the shooting times of the images selected by the image selection processing unit 7 are corrected.

The timer processing unit 9 counts the elapsed time from immediately after photographing for each image. This count value is stored in the main memory 6 when the time of the built-in clock is set, when a picture is taken, and when the built-in clock is corrected.
Is stored and managed as time management data 6b, and is used to correct the image capturing time.

The clock processing unit 10 is a built-in clock provided in the video equipment, and the time is set based on the operation and the command input from the input means 1. Further, at the time of shipping, resetting, replacement of the recording medium 5, etc., the initial setting is, for example, January 1, 2000.

The process of adjusting the photographing time in the photographing time correcting device of the video equipment of this embodiment will be described below.

FIG. 2 is a flow chart for explaining the method of adjusting the photographing time of the video equipment of this embodiment.

In step S1, the process related to the correction of the photographing time is started, and in step S2, the recording medium is set in the initial state in which the time is not set, such as at the time of shipping, when the video equipment is reset, or the like. 5 is attached to the main body of the video equipment.

In step S3, the CPU 4 determines whether the recording medium 5 is once removed from the device body after photographing.
It is judged by. When it is determined that the recording medium 5 is once detached from the device body, the image capturing time of the image stored in the recording medium 5 and the time of the device body built-in clock have no relation to each other. Therefore, the correction processing of the photographing time according to the present invention cannot be performed.
Therefore, if it is determined in step S3 that the recording medium 5 is once removed from the device body, the timer processing unit 9 resets the timer in step S4,
The process ends in step S14. The timer is also reset when the video equipment is reset.

On the other hand, if it is determined in step S3 that the recording medium 5 has not been removed from the device body, the image 5a obtained by picking up the image of the subject with the video device is stored together with the shooting time 5b. Stored in media 5. In the video device of this embodiment, step S7.
When the subject is photographed in step S8, the timer starts counting in image units in step S8, and the elapsed time immediately after the photographing is counted. Therefore, if the current accurate time can be known, the time at which the image was captured is accurate. Can be adjusted to the time.

When it is determined in step S3 that the recording medium 5 has not been detached from the main body of the device, when the operation and instruction are input from the input device 1 to set the time of the built-in clock in step S5, In S9, the clock processing unit 10 updates the current time. Also, step S
At 10, the time adjustment processing unit 9 causes the main memory 6
Of the time management data 6b stored in, the values other than 0 are corrected and updated by the time difference from the time when the value of the time management data was previously updated. Here, for the image data whose shooting time has already been corrected, the value of the time management data 6b is reset in step S13, so the time management data 6b is not updated. Further, in the image taken after the time setting, the value of the time management data 6b becomes 0 even if it is not corrected, and the time management data 6b is not updated.

In step S11, of the image data 15 recorded in the recording medium 5, the one whose photographing time 5b is to be corrected is selected. In step S12, the one stored in the main memory 6 is selected. The shooting time of the captured image is corrected to the time obtained by subtracting the value of the counter in the timer processing unit 9 from the current time. Then, the shooting time 5b of the selected image recorded in the recording medium 5 is corrected and updated. Since the time management data 6c of the image corrected to the correct shooting time does not need to be managed at this time, the time management data 6c of the corrected image stored in the main memory 6 is reset in step S13. , The write-protected state is set so that the value is not entered again.

Further, if the time of the video equipment is not set in step S5 and the user corrects the shooting time of the image shot in the past, an operation or instruction is given from the input device 1 in step S6. By inputting, the image data 15 recorded in the recording medium 5 whose image capturing time 5b is to be corrected is selected, and the image capturing time of the selected image is changed from the current time to the counter of the timer processing unit 9. It is corrected to the time obtained by subtracting the value.

When the photographing shutter is pressed in step S7 regardless of whether the time of the video equipment is set in step S5 and the photographing time is corrected in step S6, the image 5a and its image are recorded on the recording medium 5. Shooting time 5b
The image data 15 consisting of is recorded, and the image data 6c and the time management data 6b are recorded in the main memory 6. As the time management data 6c, the elapsed time from the time of shipment, the time of reset, the time of changing the recording medium, etc. to the time of shooting is recorded. Further, the time of the built-in clock is recorded in the recording medium 5 as the image capturing time regardless of whether the time is set in the built-in clock of the video equipment. In addition, since the counter value is used in steps S10 and S12 when the time of the video device is set and the shooting time is corrected next, the timer processing unit 9 starts the timer counting operation immediately after shooting. It This timer counts the time immediately after shooting for each image, and is managed by the timer processing unit 9 until the recording medium 5 is removed from the video equipment main body or the video equipment is reset. Counting operation is performed.

As described above, since the time is counted by the timer for each image, even when a plurality of images are taken at the time of later correcting the image taking time, each image is taken one by one. The shooting time can be corrected for any image.

FIG. 3 is a schematic diagram for explaining the flow of processing for correcting the photographing time of the image photographed in the initial state in which the built-in clock is not set in the digital still camera of this embodiment.

When the digital still camera is shipped, when the digital still camera is reset, or when the recording medium 5 is removed from the video equipment main body in order to change the recording medium 5, it is usually built in the digital still camera. The time of the built-in clock is in the initial state,
For example, even if the actual time is, for example, 8:20 on May 17, 2001 as shown in (21) of FIG. 3, the built-in clock is as of January 1, 2000 as shown in (22) of FIG. The default setting is 0:00.

In this initial state, after a certain fixed time, for example, 2 hours and 5 minutes a day as shown in (23) of FIG. 3,
As shown in (24) of FIG. 3, May 18, 2001, 10
When the subject is photographed and the data such as the image and the sound are recorded at the time of 25 minutes, the photographing time 5b of the image recorded in the recording medium 5 at this time is the actual time ((2
4) Unlike May 18, 2001 10:25),
Relative time when a fixed time ((23) 1 day 2 hours 5 minutes) has passed from the initial state ((22) January 1, 2000 0:00), that is, as shown in (25) of FIG. 2000
It will be 2:05 on January 2nd.

When an image is taken, regardless of whether the time of the built-in clock is in the initial state or not, the image data 15 consisting of the image 5a and its shooting time 5b is recorded in the recording medium 5 and the image is taken. The elapsed time from the time is counted. The elapsed time is used later when setting the time of the built-in clock, when correcting the built-in clock, and when updating the shooting time of an image taken in the past.

For example, after photographing the subject, for a certain period of time, for example, as shown in (26) of FIG.
When the user sets the time of the built-in clock in the digital still camera at 11:35 on May 25, 2001, as shown in (27) of FIG. The shooting time of the image stored in the main memory 6 is the current time at the time setting ((27) May 25, 2001, 11:35), as shown in the equation (a) in the figure.
From the counter of the timer processing unit 9,
The time obtained by subtracting the elapsed time (immediately after the photographing of the subject until the next time setting ((26) 7 days 1 hour 10 minutes), that is, as shown in (28) of FIG.
It is corrected at 10:25 on the 18th of the month, and the shooting time of the image stored in the storage medium 5 is corrected to the correct shooting time that reflects the time setting of the built-in clock.

After setting the time of the built-in clock of the digital still camera, for example, as shown in (29) of FIG.
Even when the image is taken at 12:45 on May 27, 2001, as in the case of the previous image, the time of the built-in clock is set to 2 as shown in (30) of FIG.
The recording medium 5 is recorded at 12:45 on May 27, 001. At this time, the photographing time of the image photographed before is continuously managed as the last-corrected time, that is, 10:25 on May 18, 2001 as shown in (31) of FIG.

In this way, the correct photographing time can be recorded and managed in the recording medium 5 for both the image photographed before the time setting of the built-in clock and the image photographed after the time setting in the video equipment. The user can easily edit and manage the data. Note that the time management data is not used in this example.

FIG. 4 is a schematic diagram for explaining the flow of processing for correcting the photographing time of an arbitrary image photographed in the past after photographing a plurality of images in the digital still camera of this embodiment. . In FIG. 4, the storage medium 5
Shows an example in which image data of four images is stored.

The first image is taken in an initial state in which the time of the digital still camera is not set, and the recording medium 5 has a shooting time relative to the initial state in January 2000. 2:05 a day is recorded. Further, in the time management data of the first image, 9 days, 2 hours, and 20 minutes, which is the elapsed time from immediately after shooting to the previous time setting, are recorded and managed. Further, the second image has been shot after the time setting of the digital still camera has been performed or the shooting time has been corrected, and the time setting is reflected as the shooting time on the recording medium 5. The time is 10:27 on May 18, 2001, which is the time recorded. The time management data of the second image is reset to 0 days, 0 hours, and 0 minutes. The third image is taken in an initial state in which the time of the digital still camera is not set, and the recording medium 5 has a shooting time that is a relative time from the initial state.
It is recorded at 2:10 on January 1, 2000. Further, in the time management data of the third image, 9 hours, 2 hours, and 15 minutes, which is the elapsed time from immediately after the shooting until the previous time setting, are recorded and managed. Further, the fourth image has been shot after the time setting of the digital still camera has been performed or the shooting time has been corrected, and the time setting is reflected as the shooting time on the recording medium 5. It is 12:45 on May 27, 2001, which is the time when it was recorded. Further, the time management data of the fourth image is reset to 0 days, 0 hours, and 0 minutes.

The time when the last image was taken, for example, 12:45 on May 27, 2001, as shown in (41) of FIG.
From the minute, a certain fixed time, for example, 2 days and 3 hours and 10 minutes as shown in (42) of FIG. 4 has passed, and it has become 15:55 on May 29, 2001 as shown in (43) of FIG. At this time, when the photographing time of the third image is to be corrected, the user operates the input device 1 and inputs a command, so that 3 out of the image data recorded in the main memory 6 is selected. The image data of the first image is selected. Then, as shown in the equation (b) in the figure, the shooting time of the image recorded in the main memory 6 is the time when the last shooting was performed ((41) May 27, 2001, 12:45). )
Time obtained by subtracting the value of time management data (9 hours, 2 hours and 15 minutes) from (10:30 on May 18, 2001)
And the shooting time of the image stored in the storage medium 5 is corrected to the correct shooting time. At this time, the value of the time management data (9 days, 2 hours and 15 minutes) of the third image stored and managed in the main memory 6 is:
It is reset and returns to 0 (0 days 0 hours 0 minutes). Once the time management data is reset and returns to 0, there is no need to manage the time difference from the built-in clock, so the time management data will not have a value again.

At the same time, ((43) 2001
(May 29, 15:55), when the time setting of the built-in clock in the video equipment (time setting for the second time or later) is performed, the shooting time is corrected, for example, for the first image. The value of the time management data of the non-excluded image is, as shown in the equation (c) in the figure, the elapsed time from the previous shooting to the present, which is counted by the timer of the timer processing unit 9 ((42) 2 days). 3 hours and 10 minutes) and the time that has been managed as time management data for the first image so far (9 days 2
It is updated to the time (5 hours and 30 minutes on 11th) obtained by adding (20 minutes).

As described above, even if the photographing time has been corrected in the past, the image of which the value of the time management data has been reset to 0 has not been corrected unless the storage medium is removed. Can be managed in a possible state.

FIG. 5 is a schematic diagram for explaining the flow of processing for managing image data by time management data after photographing a plurality of images or setting time in the digital still camera of this embodiment. It is a figure.

When the digital still camera is reset,
The built-in time is 0 January 1, 2000 as shown in (52) of FIG.
From the time when it is in the initial state such as 0 hour, for example, 8:20 on May 17, 2001, as shown in (51) of FIG. 5, for a certain fixed time, for example, as shown in (53) of FIG. When 2 hours and 5 minutes have passed for one day and 10:25 on May 18, 2001, as shown in (54) of FIG. 5
The shooting time of the image recorded in is the first image (200
2:05 on January 1, 2000) Second image (2000, January 1)
As for the third image (January 1, 2000, 2:10), as the third image (January 1, 2000, 2:10), 2 minutes after the first image, 3 minutes later Will be recorded.
Further, the time management data is the first image (-
Day-hour-minute ()), second image (0:02 on day 0), 3
It is recorded like the first image (0:05 on the 0th day). Here, the time management data of the first image (-day-hour-minute)
Is a value different from 0.

The photographing time recorded in the recording medium 5 at this time is a relative time from the initial state, and is the time at which the photographing was actually performed ((54) May 18, 2001).
It's not 10:25 a day. Therefore, as the elapsed time from immediately after shooting until the time setting of the video equipment is performed next,
As shown in (55) of FIG. 5, an accurate shooting time is calculated by counting 7 days, 1 hour, and 10 minutes by the counter of the timer processing unit 9.

Further, the value of the time management data of the fourth image is 0
It is set to 0:00 on the day.

As described above, since the correct photographing time can be recorded and managed in the recording medium 5 for both the image photographed before the time setting of the video equipment and the image photographed after the time setting, the user can manage the data. Editing and management can be done easily.

FIG. 6 is a diagram for explaining the flow of processing for correcting the shooting time of an image taken in the past when the time of the built-in clock of the video equipment is corrected in the digital still camera of this embodiment. It is a schematic diagram.

In the processing examples described with reference to FIGS. 3 to 5, the image data is recorded in the recording medium every time the built-in clock of the video equipment is set to correct the image capturing time. The image whose shooting time is to be corrected is selected from the multiple images that are present, but in the following processing example, the image is not selected, and only when you want to update the time of individual images, select the image. To do.

In FIG. 6, when the time of the built-in clock in the digital still camera is set, for example, (6 in FIG.
As shown in 1), the image data of three images is stored in the storage medium 5 at 15:55 on May 29, 2001.

The first image is taken in the initial state in which the time of the digital still camera is not set, and the recording medium 5 has a shooting time relative to the initial state in January 2000. 2:05 a day is recorded. Further, the time management data of the first image records and manages 11 hours, 5 hours and 30 minutes, which is the elapsed time from immediately after the shooting until the previous time setting. Further, the second image has been shot after the time setting of the digital still camera has been performed or the shooting time has been corrected, and the time setting is reflected as the shooting time on the recording medium 5. The time is 10:27 on May 18, 2001, which is the time recorded. The time management data of the second image is reset to 0 days, 0 hours, and 0 minutes. Further, the third image has been shot after the time setting of the digital still camera has been performed or the shooting time has been corrected, and the time setting is reflected as the shooting time on the recording medium 5. It is recorded at 10:30 on May 18, 2001, which is the time when it was opened. Further, the time management data of the third image is reset to 0 days, 0 hours, and 0 minutes.

When the time of the built-in clock of the digital still camera is set ((61) May 29, 2001 15)
At 55 minutes), the built-in clock has been set previously and the current time of the built-in clock is 15:52 on May 29, 2001. At this time, the user operates the input device 1 and inputs a command in order to correct the time of the built-in clock.
6 minutes, a certain fixed time, for example, 3 minutes as shown in (62) of FIG. 6, and 2001 as shown in (63) of FIG.
The time will be corrected at 15:55 on May 29, 2015.

At this time, for example, like the first image,
An image in which the value of the time management data (5 hours and 30 minutes on 11th) stored and stored in the main memory 6 is not 0 (an image in which the time setting of the video equipment is not accurately set at the time of shooting, or the shooting time is The image which has not been corrected to the correct time) is added to the value of the time management data by the time difference ((62) 3 minutes) between the time before the correction and the time after the correction 11
It is 5 hours and 33 minutes a day. Here, when the built-in clock is delayed, the time difference between the time before correction and the time after correction is subtracted from the value of the time management data.

Further, like the second image and the third image, the images in which the value of the time management data stored and stored in the main memory 6 is 0 (the time setting of the video equipment is accurately set at the time of shooting). The image of which the time is set to the correct time), the value of the time management data is reset to 0, and the writing is prohibited. In these images, the time of the built-in clock is reflected in the shooting time, so the shooting time (200
10:27 on May 18, 1st, and May 18, 2001
At 10:30 on the day), the time difference between the pre-correction time and the post-correction time ((62) 3 minutes) is added to obtain 2 respectively.
It will be 10:30 on May 18, 001 and 10:33 on May 18, 2001. Here, when the built-in clock is delayed, only the time difference between the time before correction and the time after correction is subtracted from the shooting time.

When the time of the built-in clock is corrected, the photographing time is always corrected in the next step. Time setting ((61) May 29, 2001 15:05
5 minutes), a certain period of time, for example, 1 hour and 3 minutes a day as shown in (64) of FIG. 6, has passed, and as shown in (65) of FIG. At 16:58 on the 30th, as in the processing example of FIG. 5, the user inputs an operation or command from the input device 1,
Of the three images whose image data is recorded in the main memory 6, the first image is selected and the shooting time is corrected. In this case, the shooting time of the image recorded in the main memory 6 is set to the previous time from the current time (11:35 on May 30, 2001) as shown in the equation (d) in the figure. The elapsed time from the time until the shooting time is adjusted (1 day, 1 hour and 3 minutes) is subtracted, and the value of the time management data (5 days and 11 minutes, 11 days) updated by the correction of the internal time is subtracted Time obtained (May 1, 2001)
It will be revised at 10:25 on the 8th. At this time, the value of the time management data of the first image stored and managed in the main memory 6 is reset and returns to 0 (0 day 0 hour 0 minute).

As described above, even in the case of images photographed in the past, the time difference between the photographing time of the image stored in the recording medium 5 and the time of the built-in clock is managed in the main memory as time management data. As a result, the shooting time can be managed in association with the time of the built-in clock.

[0080]

As described in detail above, according to the present invention,
In video equipment that records images, sounds, etc., the time elapsed immediately after the subject is photographed is counted, and by subtracting this count value from the current time, it is stored in the recording media of the video equipment, in the past. It is possible to arbitrarily correct the shooting time of the shot image. Therefore,
Even when the time of the built-in clock is not set correctly at the time of shooting, it is possible to correct the shooting time of the images shot in the past to the correct time. Further, when the built-in clock is set and corrected, the set time of the built-in clock and the contents of the correction can be reflected in the shooting times of images taken in the past. Therefore, it is possible to create image data having an accurate shooting time without the user manually editing the image data, and it is possible to easily edit and manage the image data.
